shape of particle

Shape features of coarse aggregates include contour shape, angular features and surface texture. Contour shape represents the overall shape ratio of a particle, angular feature is the prominent degree of the angular on the profile, and texture describes the surface roughness of a particle.

粗集料形态特征包括轮廓形状，棱角特征和表面纹理，轮廓形状表征的是颗粒的整体形状尺寸比例，棱角性表征的是颗粒轮廓上棱角的突出程度，纹理描述的是颗粒表面的粗糙度。
